Spontaneous pneumomediastinum due to achalasia: a case report.

Spontaneous pneumomediastinum (SPM) is a rare and benign clinical entity characterized by free air around mediastinal structures. Precipitating factors include violent cough, asthma, inhalational drugs, labor and exercise. We report a case of SPM due to achalasia which to the best of our knowledge, has never been reported. In achalasia, Valsalva maneuver might accompany severe vomiting. This causes alveolar rupture due to elevated intrabronchial and intra-alveolar pressure. Air tracks along the mediastinal spaces cause SPM. In our patient, there was no evidence of esophageal perforation. Tension pneumomediastinum and pneumothorax are complications of SPM.

[Esophageal dilatation using the Savary-Gilliard sound set].

Authors present a method of esophageal dilatation and report their experiences. The place of esophageal dilatation among other therapeutic approaches of esophageal stricture is discussed. The advantage of Savary-Gilliard bougies and guide wire and its applications are presented. During one and a half year 218 esophageal dilatations were performed at 82 patients. 11 patients were intubated endoscopically. Esophageal perforation occurred in 2 cases (0.93%). Dilatation of the esophagus with Savary-Gilliard bougies and using of the guide wire are considered a safe and many-sided method in the diagnosis and treatment of esophageal strictures.

Boerhaave's syndrome presenting with abdominal pain and right hydropneumothorax.

This case of Boerhaave's Syndrome had several unusual features including a delayed presentation and right-sided esophageal perforation. The patient's initial episode of hematemesis may have been caused by a small mucosal laceration in the area of the Barrett's lesion that later ruptured. On the other hand, if initially there was an esophageal rupture, it did not violate the parietal pleura or mediastinum. The overlying pleura remained intact until digested by gastric contents, thereby causing a right-sided hydropneumo thorax and a marked increase in symptoms, which promoted the patient to come to the ED. Because the patient initially appeared stable and had a history of emesis 4 days before presentation, and because an initial chest X-ray interpretation overlooked the right-sided apical pneumothorax, Boerhaave's Syndrome was not considered initially. Aspiration pneumonia, pancreatitis, alcoholic gastritis, or active peptide ulcer disease were in our initial differential. It was only after the repeat chest X-ray, which more obviously showed the pneumothorax, and insertion of the chest tube that the correct diagnosis was made. Had the pneumothorax not been overlooked initially, the diagnosis may have been made earlier. It is apparent from this case and a review of the literature that Boerhaave's Syndrome is an uncommon clinical entity and has varying modes of presentation, making the diagnosis a difficult clinical challenge. Boerhaave's Syndrome should be considered in all ill-appearing patients presenting with the combination of gastrointestinal and respiratory complaints. The single most important test may be the upright chest X-ray. However, if it is normal, and there is a high index of suspicion, esophagograms and or chest CT may be required to demonstrate the lesion. Because survival is directly related to the time to diagnosis and treatment, a high clinical suspicion can decrease the substantial morbidity and mortality associated with Boerhaave's Syndrome.

Radiologic placement of metallic esophageal stents: preliminary experience.

OBJECTIVE: To assess the usefulness of covered, self-expanding metallic stents for alleviating stricture associated with malignant esophageal lesions. PATIENTS AND METHODS: Self-expanding metallic stents were placed in 10 patients with dysphagia related to stricture caused by malignant esophageal lesions. The stents were placed fluoroscopically with local anesthesia, and patency of the esophageal lumen was assessed by barium study after the procedure. The patients were then followed clinically. RESULTS: In all 10 cases patency of the lumen was renewed after stent placement. After the procedure 9 of the patients could tolerate a normal or near-normal diet; in the other patient esophageal perforation occurred, and clinical deterioration prevented oral intake of food. In one patient, 2 stents were needed because of the length of the stricture. Two patients experienced reflux after placement of the stent across the gastro-esophageal junction. Another patient had asymptomatic aspiration after stent placement in the proximal esophagus. In 2 patients, symptoms associated with tracheoesophageal fistula were relieved after placement of the stents. Six of the 10 patients died; mean survival after the procedure was 12 (range 1 to 56) weeks. The other 4 patients were alive at the time of writing, having survived for a mean of 7.5 (range 2 to 13) weeks; all of these patients tolerated a near-normal diet. CONCLUSIONS: The placement of covered, self-expanding metallic stents is a quick, effective method of palliating dysphagia related to stricture caused by malignant esophageal lesions.

[A thoracic aortic aneurysm with respiratory failure caused by the mechanisms of stenosis of the left bronchus and ipsilateral pulmonary artery--report of a case and review of the literature].

Clinical symptoms of thoracic aortic aneurysm vary widely from symptoms resulting from its rupture to those due to compression of surrounding organs. Furthermore, the onset of symptoms is frequently followed by a fatal outcome unless emergency measures are taken. We have recently experienced a patient who developed respiratory insufficiency caused by an aneurysm of the descending thoracic aorta compressing the left primary bronchus and the right pulmonary artery, the former causing ventilatory failure in the left lung and the latter interfering with blood flow in the right lung. The patient underwent emergency prosthetic graft replacement and showed temporary symptom improvement. However, a postoperative complication of esophageal perforation due to ischemic necrosis occurred and eventually caused acute empyema followed by death. The patient was a 48-year-old male who presented with symptoms similar to bronchial asthma. Angiographic examination (iv-DSA) revealed compression of right pulmonary artery by an aneurysm of the descending thoracic aorta. Bronchoscopic findings included extramural stenosis of the left bronchus accompanied by arterial pulsation. As an emergency measure, artificial blood vessel replacement of the descending thoracic aorta was performed. However, the patient developed postoperative acute empyema and died on the 19th postoperative day. Autopsy revealed ischemic necrosis on the esophageal wall where the aneurysmal lesion had touched before operation. This seems to have formed a perforation into the left thoracic cavity and ultimately to have caused acute empyema. Since we believe that the pathogenesis and clinical course observed in this patient is rather rare, the case is reported in accompanied by relevant data from the literature.

Esophageal foreign bodies in the pediatric population: our first 500 cases.

BACKGROUND: Children with esophageal foreign bodies are frequently seen by pediatric surgeons. Choking and dysphagia are common presentations; however, esophageal perforation has been reported. Historically, rigid esophagoscopy with extraction of the foreign body has been the recommended treatment. Alternatively, Foley balloon extraction is a safe and effective approach. METHODS: Over a 16-year period, 555 children presented with an esophageal foreign body. Retrospective analysis of the medical record was undertaken. Statistics were by univariate analysis. RESULTS: Two hundred ninety-eight boys and 257 girls presented with a mean age of 3.24 years. Dysphagia (37%) and drooling (31%) were the most common symptoms. Foreign bodies were lodged in the superior esophagus in 73%, and 88% of the objects were coins. Balloon extraction with fluoroscopy was performed in 468 children. Eighty percent of the objects were successfully removed with a mean fluoroscopy time of 2.2 min, and 8% were advanced into the stomach. The overall success rate was 88%, with failures necessitating rigid esophagoscopy under general anesthesia. Children younger than 1 year were the most likely to fail (25% failure rate). Airway aspiration never occurred. Significant savings in patient charges were observed with this approach. CONCLUSIONS: Balloon extraction of pediatric esophageal foreign bodies is a safe and cost-effective procedure. This technique is applicable for infants, children, and adolescents. Experienced practitioners should be able to achieve greater than 80% success rate.

[The endoscopic therapy of benign stenoses of the esophagus and cardioesophageal junction using Eder-Puestow instrumentation].

The results of palliative endoscopic treatment by bougienage using Eder-Puestow instrumentation, performed in a limited contingent of patients presenting benign esophageal strictures, are analyzed. It is underscored that the method is readily carried out and effective, and seldom leads to noteworthy complications, such as esophageal perforations--one patient alone presenting cicatricial stricture out of the total of 42 cases given treatment with bougienage over a 10-year period. The commonest cause of benign strictures of the esophagus in the series being examined is reflux (peptic) esophagitis against the background of hiatus hernia.

Endoscopy-guided balloon dilatation of esophageal strictures and anastomotic strictures after esophageal replacement in children.

This study evaluates the safety, efficacy, and technical problems of the new technique of endoscopy-guided balloon dilation (EGBD) in the treatment of strictures of the esophagus and its replacement. Between 1986 and 1990, the authors treated 33 children (aged 3 weeks to 20 years) with EGBD; 18 had esophageal strictures (primary esophageal atresia repair, 13; reflux esophagitis, 5), 13 had anastomotic strictures after esophageal replacement (colon, 12; stomach, 1), and 2 had caustic strictures. The majority (23 of 33) had previously failed to respond to conventional bouginage (mean, 11.2 sessions; range, 1 to 32 sessions). EGBD was performed using flexible endoscopy and flouroscopic screening under general anesthesia. Endoscopy identified and resolved the errors or uncertainties of preoperative contrast studies in 7 patients, 5 of whom had colon interposition. EGBD was achieved in all 31 patients with esophageal or replacement strictures; the mean number of EGDB procedures per patient was 2.1 (range 1 to 7). Symptomatic relief was excellent in 24 and moderate in 7 patients. Both patients with caustic strictures had esophageal perforation from EGBD (excessive inflation, 1; false passage of guide wire, 1). Patients who had experienced both conventional bouginage and EGBD noticed less pain with EGBD and resumed eating sooner. The authors conclude that EGBD is safe and effective for treating esophageal and replacement strictures but not caustic strictures.

Effects of neutralizing agents on esophageal burns caused by disc batteries.

The sequelae associated with ingested disc batteries that lodge in the esophagus may include tracheoesophageal fistula, esophageal perforation, stricture formation, or death. The focus of the current investigation is on whether medical therapy can arrest or lessen the severity of the injury during the time required to transport the patient to a center for treatment. A case of esophageal damage from the ingestion of a 1.5-V manganese dioxide disc battery in a 3-year-old boy is reported also. A two-phase study was completed in which the initial phase was an in vitro experiment to identify potable solutions that might neutralize the alkali contained in disc batteries. An in vivo study in 24 cats was undertaken to determine if bolus administration of these solutions would arrest or lessen the severity of the esophageal injury. None of the solutions tested demonstrated a significant difference in the degree of gross or histologic esophageal damage when compared to controls.

Incomplete duplication of the esophagus: a case report.

A case of incomplete duplication of the esophagus diagnosed in a 20-month-old girl with an esophageal perforation is presented. X-ray films of the chest showed pneumomediastinum and subcutaneous emphysema. A water soluble contrast esophagogram revealed a contrast leakage from the cervical esophagus to the thoracic inlet. The endoscopic findings are described. Complete resection of the esophageal duplication was effective.

Surviving Boerhaave's syndrome without thoracotomy.

A case of Boerhaave's syndrome managed without thoracotomy is described. The diagnosis was not confirmed for 24 h when a barium swallow revealed free rupture of the esophagus into the left pleural cavity. Although survival has been reported with nonoperative management of contained esophageal perforations, to our knowledge, this is the first report of surviving Boerhaave's syndrome with free pleural rupture, without thoracotomy.

Nitinol esophageal stents: new designs and clinical indications.

PURPOSE: To evaluate the clinical use of covered and noncovered, knitted nitinol stents in patients presenting new stent indications. METHODS: Self-expandable, knitted nitinol stents were implanted in four patients for treatment of dysphagia. In two patients who had malignant strictures and had esophago-respiratory fistulae and in one patient with an esophagocutaneous fistula, polytetrafluoroethylene (PTFE)-covered stents were implanted. One patient received a noncovered stent, but a retrograde approach through a percutaneous endoscopic gastrostomy (PEG) fistula had to be chosen for recanalization of an esophageal occlusion. Two patients received stents for treatment of benign strictures. RESULTS: Recanalization of the stricture and stent implantation were performed under fluoroscopic control without any procedure-related morbidity or mortality. Dysphagia improved in all patients and the esophageal fistulae could be sealed off by covered stents. During a maximum follow-up of 18 months, there was no stent migration or esophageal perforation. Complications observed were stent stenosis due to food impaction (1/4) and benign stent stenosis (2/2). Most complications could be treated by the interventional radiologist. CONCLUSION: Self-expandable, covered Nitinol stents provide an option for the treatment of dysphagia combined with esophageal fistulae. In combination with interventional radiology techniques, even complex strictures are accessible. For benign strictures, the value of stent treatment has not yet been proven.

Evaluation and management of diseases of the esophagus.

Current methods to evaluate patients with esophageal disease include barium swallow with fluoroscopy, which is useful in demonstrating structural defects. Disordered motility is better evaluated with a cine-esophagram. Recent application of radioisotopes has been useful in evaluation of esophageal reflux and the post-treatment of achalasia. Esophageal motility studies may evaluate lower esophageal sphincter and upper esophageal sphincter pressures and the response of the body of the esophagus to series of swallows. Since there is no "gold standard" for the evaluation of reflux esophagitis, some of the tests designed to evaluate reflux and the patient's reaction to acid in the esophagus include the acid infusion test, the standard acid reflux test, the acid clearance test, and 24-hour pH monitoring. Endoscopy with either the flexible or the rigid instrument is important for the diagnosis of obstruction or esophagitis and allows direct visualization of the esophagus. The treatment of reflux esophagitis is discussed. The differential diagnosis of dysphagia may include achalasia, diffuse esophageal spasm, and mechanical obstruction of the esophagus due to rings, webs, strictures, and benign or malignant tumors. The evaluation of dysphagia should include radiologic as well as endoscopic evaluation. Treatment of obstruction varies according to the nature of the lesion. The Mallory-Weiss syndrome or bleeding from the mucosal tears of the gastroesophageal junction and Boerhaave's syndrome, spontaneous esophageal perforation, are two disorders associated with vomiting. The Mallory-Weiss syndrome usually resolves without specific therapy, but a high index of suspicion is required for patients with chest pain after vomiting, as spontaneous perforation necessitates immediate surgery. Most diverticula need no treatment, but the Zenker diverticulum, if symptomatic, should probably be surgically repaired.

Computer-assisted robotic heller myotomy: initial case report.

PURPOSE: Our objective was to determine the efficacy of computer-assisted robotic laparoscopic Heller myotomy. METHODS: A 76-year-old woman with a significant history of achalasia was evaluated for laparoscopic Heller myotomy. The daVinci surgical system was used throughout the procedure. RESULTS: Computer assistance allowed scaling of hand motions from a range of 2:1 to 5:1. Successful dissection of the esophageal musculature was accomplished, and a Toupet-type fundoplication was performed. The patient was discharged from the hospital the day after surgery with five port incisions, each <1 cm. CONCLUSIONS: Telemanipulator computer-assisted surgical devices may have applications in procedures that require advanced and finely tuned motions, such as Heller myotomy. The benefits of extra magnification and three-dimensional imaging can help prevent esophageal perforation and identify residual circular muscle fibers.

[Esophageal amyloidosis secondary to rheumatoid arthritis simulating achalasia].

The involvement of the esophagus in amyloidosis secondary to rheumatoid arthritis is rare. The case of a female patient with rheumatoid arthritis and secondary esophageal amyloidosis (type AA) with a radiologic and endoscopic clinical picture compatible with achalasia is presented. In the manometry carried out after two cardiomyotomies, abundant non propulsant tertiary waves were seen, as were two primary waves, intraesophageal pressure higher than that of the gastric fundus and lower hypertensive esophageal sphincter which was completely relaxed on one occasion, resulting in a manometric pattern which was different to that of the other two cases published with the same disease. Endoscopic cardiomyotomies and dilatations were performed. The patient died after 2 years due to post dilatation esophageal perforation. The manometric findings are compared with those of the two previous similar cases with emphasis being made in that the anarchic arrangement of the amyloid in the esophagus produces different unforeseen and uncharacteristic motility patterns. The authors only found in the literature two cases of esophageal amyloidosis secondary to rheumatoid arthritis simulating achalasia.

Emergency transumbilical embolization of bleeding esophageal varices.

Eight patients had major hemorrhage from esophageal varices; in seven, one or two embolizations of the coronary and short gastric veins resulted in cessation of hemorrhage. This procedure can be used in patients with massive ascites, severe coagulopathy, or profound liver failure, as the access route through the dilated umbilical vein can be reached via a supraumbilical incision done with the patient under local anesthesia. All patients died; two deaths were attributable to complications of the procedure, the other six to the severity of the cirrhosis. Sclerotherapy may be combined with coronary vein embolization, but the risk of esophageal perforation may be greater than with sclerotherapy alone.
